An Experiment is performed to examine the possibility of a plasma injector through a divertor which makes use of the magnetic energy dissipation and strong plasma heating in a magnetic neutral point discharge. A divertor type magnetic field is produced in a straight magnetic field. An intense plasma current is induced along the circular magnetic neutral line of the divertor field, and the plasma is heated and injected inward to the central region of the magnetic field. The energy of the plasma diffusing along magnetic field lines is measured by a time of flight method using a pair of electrostatic double probes, and it is shown that the average of the diffusing plasma ions is 200 eV and that the total amount of injected particles is 6×10
16 particles per shot. Prospect of the divertor injector for a fusion reactor is discussed.
